A game apparatus (10) provides a game that, on the basis of a game history of a player, conditions an amount for the player to move a body part of the player, and thereby moves an object arranged in a virtual space. The object is related to a conditioning parameter and a position in the virtual space. The acceptor (12) detects a position of a predefined body part of the player in a real space. The obtainer (13) obtains a movement direction and a movement distance of the predefined body part from detected positions. The mover (14) moves the object in the movement direction on the basis of the obtained movement distance, the conditioning parameter, and the position of the object. The changer (16) changes the conditioning parameter depending on a history of the player.
